` ing the parts of the mould together when the reciprocating member is brought toward the mould.

Other objects and advantages of the invention will more fully appear from the following description taken in connection with the accompanying drawings, in which:

Fig. V1 is a' side elevation showing a preferred embodiment of my invention, 4parts being broken away and in section.

Fig. 2- is a fragmentary view showing in front elevation the' operating portion of the machine shown in'Fig. 1, parts being broken away and'in section.

Fig. 3 is a sectional lview on line 33 of *3o Fig. 2.

Fig. 4 is a fragmentary View as viewed on the line 4--4 of/Fig. 2.V

Fig. 5 is asectional View illustrating one form of aV vibrating mechanism talren on line 5,-5 of Fig. 3.

Referring to the drawings, the reference numeral 10 designates a base structure having a vertical supporting member 12 with a pairof oppositely disposed guide members 4o 14 secured to the vertical member 12, such as by bolts 16. Supported on the vertical member 12 is a cylinder 18 in which is mounted a piston 2() adapted to be reciprocated by an airpressure through suitable connections 22 from a valve 24, which is supplied with the 1929. Serial No. 381,620.

air pressure from a pipe 26. A handle 28 is adapted to control the valve 24 whereby air may be admitted to the cylinder 18 moving the piston 2O downwardly in the cylinder 18 and air may be admitted through pipes 30 for raising the piston upwardly in the cylinder 18.

On the lower end of a piston rod 32 I have secured a block 84 which is guided between the guides 14. The under surface of the block 34 is provided with a plurality of openings 86 which receive plungers 38 in the form of pins held in the openings 36 by removable screws 40. A screw 42 detachably secures the block 84 on the lower end of the piston rod o 32. A collar 44 is received around the plunger 38.

Mounted on the base 10, below the block 34, I have provided a support 46 for the mould. A forward abutment 48 is secured 65 to the support 4G, such as by screws 50, and a rear abutment 52 is secured to the support 46 by screws 54. The rear abutment 52 is provided with an upper and inwardly extending iange 56. Between the flange 56 and the 70 support 46 is an intermediate abutment 58 which is slidable toward or away from the abutments 4.8 and 52. The intermediate abutment 58 is provided with an opening 60 having one side of the opening tapered as '75 shown at 62. An opening 64 is provided in the flange 56 registering with the opening 60. Bolts 66 extend through the rear abutment 52 and are screw threaded into the intermediate abutment 58.

A coil spring 68 is interposed between the rear face of the rear abutment 52 and the head of the bolt 66. This spring urges the intermediate abutment 58 away from the forward abutment 48, leaving a space between the intermediate abutment 58 and the forward abutment 48 for the reception of the mould.

Carried by the block 84 is al wedge member 70 adapted to be received in the openings 64 and 60. The wedge 70 is secured on the block 34 against relative downward movement by the nut 72, and is resiliently held to permit relative movement between the wedge and the block 34 by a coil spring 74 around a reduced Vportion 7 6 of the wedge member 70.

A two part mould'has been shown consisting of parts 7 8 and 80, each part being provided with semi-cylindrical recesses adapted to register with each other to form cylindrical openings 82 when the parts of the mould are together. Dowel pins 84 havev been arranged in oney of the parts to be received in openings in the other of the parts toproperly align theparts when they are brought together. The mold parts'78 and 80 are transversely slidable in a groove between the abutment 58 and the forward abutment 48 and, are positioned with the openings 82-directly under the plungers 38 by a pin y86 in the forward abutment 48. The pin is provided with a tapered end as at 88 and is resiliently urged into a correspondingly tapered opening in onel part of the mould by a spring 90. A lever 92 is pivotally mounted on the abutment 48 as at 94 and the pin 86 is pivotally mounted on' the lever 92 Vas at 96.

Secured on the block 34 is an outwardly extending flange 98 adapted for controlling a valve'l on the downward movement of the block-84. Positioned adjacent the flange 98 and inthe path of travel of the outer end of the flange 98 is a vvalve 100' which controls a vibrator 102 by opening and closing a pipe 104 connected toa supply of air pressure. When the valve is opened by the downward movement of the flange 98, pressing the lever 106 inwardly, the air pressure in the pipe 104 is conducted through a pipe 108 to the vibrator 102. The vibrator 102 is rigidly supported on a plate1110 to which is secured the supporting member 46. f

As an illustration of a'type of vibrator, l

the interior of thepiston 114 which is cylin drical and receives another piston 120. The walls of the Iiournals for the bosses 115 are providedV with openings 122 connected together andto a source of air pressure through the opening 124. Exhaust openings 126 are also formed in the .walls of the ,iournal for the bosses 115.V It will Vbe understood that when air is supplied through the opening 124 it will be admitted through the opening 118V at the right hand side of the drawing, forcing the piston 120 to the left, striking it against theleft end of the piston 114, moving it to the left. The movement of the piston 114 in this direction causes `the peripheral groove 116 to move away from the exhaust opening 122. The reverse operation then occurs, moving first the piston 120 and then the piston 114 to the right.

In the operation of the Ymachine it will be understood that when the valve 24 permits an air pressure to flow through the .pipe 22, the piston 20 is moved downwardly, carrying with it the block 34, plungers 38 and wedge 70. First the wedge 70 moves the intermediate abutment 58 against the rear :tace of the mould and forces the two parts 78 and 80 together. The flange 98 then forms a connection between the air pressure supply pipe 104 and the vibrator 102, causing the support 46 and mould to vibrate. The further movement of the piston 20 in the downward direction forces the plungers 38 into the openings 82 of the mouldA compressing any material whichrhas been placed in the openings82 of the mould.

It will be understood that various changes, including the size, shape and arrangement of parts, may be made without departing' from' the spirit of my invention and it is not my intention to limit its Vscope other than by the terms of the appended claims. VVhatIclaim is: Y

1. The method of forming an article which consists in compressing it in one direction, simultaneously compressing it in a direction at right angles to the direction of the compression in the one direction and vibrating the article during said compression.

2.v A machine of the Vclass described comprising, a base, a reciprocating member on said base, means for reciprocating said member, a two part mould supported in a position to receive a portion of said reciprocating member, means for forcing the parts of the mould togetherl when the reciprocating member is brought toward said mould, and means for vibrating said mould while the reciproeating member is being moved into said mould. Y

3. A machine of the class described comprising a base, vertical guides on said base, a reciprocating memberon said guides having a plurality of downwardly extending projections, means for reciprocating said member, a two'part mould having a plurality of openings, said mould being split longitudinally through the center of said' openings, means for locating the mouldl on said support, Yand means forcing the parts of the mould together when the reciprocating memberV is brought toward the mould.

4. A machine of the class described comprising a reciprocating member, a wedge carried'by said reciprocating member, a plurality of projectionscarrie'd by said reciprocating member, a member movable vat right angles to the move-ment of said reciprocating member, a stationary member in the path of the last named movable member, resilient means for moving said movable member away from said stationary member to provide a space to receive a member between the stationary member and the movable member, and means for reciprocating said reciprocating member whereby said wedge moves the movable member toward the stationary member and the projections are received in the member between the movable member and the stationary member.
